SPECIFICATION forming part of Letters Patent No. 610,739, datedSeptember 13, 1898.

Application filed November 24,1897 Serial No. 659,663. [No model.)

To all whom it may concern.-

Be it known. that I, FRANCIS V. GREENE, a citizen of the United States,residing in the city and county of Philadelphia, State of Pennsylvania,have invented a new and useful Improvement in Sash-Fasteners,whichimprovement is fully set forth in the following specification andaccompanying drawings.

My invention consists of an improved con struction of sash-fastener inwhich provision is made for locking the members thereof so that there isno liability of damage to the contiguous portions of the sash, theconstruction of the fastener being simplified and the number of partsreduced to a minimum.

It further consists of novel details of construction, all as will behereinafter fully set forth, and particularly pointed out in the claims.

Figure 1 represents a plan view of a sashfastener embodying myinvention. Fig. 2 represents a section on line y y, Fig. 1. Fig.

3 represents a section on lineman, Fig. 1. Figs. 4., 5, and 7 representperspective views of a member of the sash-fastener in detached position.Fig. 6 represents a plan view of a post employed in connectionwith myinvention.

Similar letters of reference indicate corresponding parts in thefigures.

Referring to the drawings, A and B designate contiguous portions of awindow-sash, the same having secured thereto the keeper 0 and member Dof the sash-fastener, respectively. The keeper 0 consists of a plate E,having the hook or catch F thereon, one side of said hook being curved,and the distance between'the plane of the curved side of said hook andsaid plate E being indicated by G. The member D of the fastener consistsof the plate H, which has the beveled or conical opening J therein, thedirectionof said bevel being indicated in Figs. 3 and 5.

K designates a post or column employed, the same having its lowerportion beveled, as at M, to correspond with the bevel of the plate I-I,said post having the opening L therein for the insertion of the journalN of the bolt T, said journal being afterward headed, as at P, asindicated in Fig. 3, so as to have the appearance of being swiveled insaid post K,

said bolt having the upturned end U, adapted to interlock with the hookF, as will be understood from Figs. 1 and 3.

V designates a finger-piece employed for rotating and locking the columnK and the member T, said finger-piece consisting of the body portion W,which is pivotally mounted on the pin X in the recess R, formed betweenthe walls S of said column and having the projection V.

Y designates a nose or stop which is adapted to contact with the memberT and thus limit the movement of the body W.

Z designates a pin or projection attached to the finger-piece V andadapted to engage orinterlock with either of the recesses or openings AB, the relative position of which will be evident from Fig. 1.

C designates a stop attached to the plate H and serving to limit themovement of the member T.

The operation is as follows: The parts are first assembled by placingthe post K within the opening J and inserting the journal N into theopening L of saidpost, after which said journal is headed, as indicatedin Fig. 3, it being apparent that the parts are prevented fromdisengagement by means of the head P and the beveled peripheries J andM. When the sashes A and B are in the position seen in Figs. 1 and 3 andthe member or look T is in the position indicated in Fig. 1, said sasheswill be locked, it being noted that the projection Z is in engagementand interlocked with the recess B. If it is desired to unlock thefastener, the finger-piece V islifted by means of the portion V, so thatthe projection Z is disengaged from the recess B, whereupon the column Kand the bolt T can be rotated in the direction of the arrows indicatedin Fig. 1, the stop 0 serving to limit the rotation of said member T,and it being apparent that when the latter has reached said stop theprojection Z can engage the opening A, thereby locking the fastener.-

It will be seen from the foregoing that when the component parts aresecured in position and the lock is screwed to the sash on raising thefinger-piece the central column can be rotated on the supporting-plate;but for locking and unlocking only about one-fourth of a circle isnecessary, the slots or recesses with a projecting stop on the uppersurface of the plate being used to limit the extent of the revolution tothis amount.

Having thus described my invention, what I claim as new, and desire tosecure by-Letters Patent, is

1. A sash-fastener consisting of a plate,havin g a column rotatablymounted therein, a bolt or member mountedin a recess in said column, afinger-piece pivotally mounted in said column adjacent to said bolt, astop for the latter, and a locking device for said finger-piece, the
